Doc,

I think the 2615 reduced a little will work just right on a 1.01 motor.

Glad you are testing the new propellers, it is much appreciated.

Thanks,

Mark Sholund

Chuck the head volume has nothing to do with burning the Pistons. Lack of fuel delivery does. In the mid 90s I ran a Grand Prix 90 in a seaducer heat raced at 72. Yes faster then still today's boats. On 33% fuel. And never took plugs.

More volume and more clearance is detuning. Believe what you want.
 
DK.. The only Aahh here...GP 90 Motor....IS LARGER HEAD VOLUME THAN EVO....

Hi Shane,

I have a 90 Seaducer that I got form Jerry Crowther/ Jeremy Edge. They were running a Back cut X467 on a VAC 91.

I put an old wore out K-90 in the boat and it spins that same prop perfectly. Great handling, good throttle response and good speed.

I tried other props, but that Back cut X467 was the best all around.

Good boating!
